cation, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to machines or apparatus for splicing thread, cord, rope or the like, and the object of the invention is to provide a machine or apparatus which will quickly and easily splice threads, cords or the like, and in such a manner as to securely bind the separate parts of the thread or cord together and to accomplish this result without materially increasing the size or transverse dimensions of the thread or cord; a further object of the invention is to provide a machine or apparatus of the class and for the purpose specified which may be held in the hand and operated by hand to produce the desired result thus permitting of the use of the apparatus at any place without interfering with other machines or machinery in connection with which the 7 thread or cord is employed, or in the manufacture of such thread or cord; and with these and other objects in view the invention consists in a machine or apparatus for the purpose specified which is simple in construction and operation and efiicient in use.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure l is a transverse section through my improved splicing machine with part of the construction shown in elevation and showing the parts in their normal and inoperative position;

of the frame is provided approximately centrally thereof with a downwardly directed handle member 16.

Passed centrally and longitudinally through the frame 10 is a shaft 17, which has a bearing in the end walls 12 and 13. Secured to the shaft 17 inwardly of the wall 12 is a large gear 18 inwardly of which is a pinion 19, and secured to the shaft 17 inwardly of'the wall 13 is a large gear 20 which corresponds in size to the gear 18.

F or the purpose of description I will call my improved machine a thread splicing machine, or a machine constructed for the purpose of splicing threads either in the manufacture of thread, or in the use of threads in manufacturing fabrics, garments'or parts of garments. The top central portion of each of the end walls 12 and 13 are recessed to receive thread holding members 21 and I 22. The threadholding member 21 consists separate parts-thereof, are provided with a radial and approximately V-shaped slot 26 which passes to the central axis of the pin 25 and into which a thread or one end portion of a thread 27 is adapted to be placed, the free end of said thread being secured in a V-shaped notch 28 in the end wall 13, as is illustrated in Fig. 3 of the drawing.

The thread holding member 22 consists of an outer disk 29 and inner pinion 30 joined bv a pin 31. The member 22, or the separate parts thereof, are provided with a radial and approximately V-shaped slot 32' 7 similar to the slot 26 and which is adapted to receive one end portion of another thread 33 to be spliced with the thread 27, the free end of the thread 33 being connected with a V-shaped notch 34 in the end wall 12 as clearly shown in Fig. 3.

Secured tothe end wall 13 is a pin 35 upon which a pinion 36 is mounted, said pinion meshing with the gear 20 and with the pinion 30 on the member 22, as clearly shown in Fig. 1.

18; l Vith this gear construction, it will be seen that the threads 27 and 33 in the operation of the machine will be unwound in 01)- posite directions, as hereinafter described;

Mounted longitudinally and centrally of the bottom' portion of the frame 10 is'an other shaft 37, the ends'of which have bearings in the end walls 12 and 13. Mounted on the shaft 37 are two brush carrying members 38 and 39, each of which consists .of cross head portions 40 in which suitable brushes 41 are mounted, and said members are provided at the r ends with downwardly directed arms 42 having enlarged bearings 43, at their lower ends through which the v the drawing.

,shaft 37 passes. The bearings 43 of the 2 0.

adjacent to the end wall 12 with an up-' wardly directed tubular rack guide 47 in which a rack 48 is vertically movable. The teeth 49 of the rack operate in connection with the pinion 19 on the gear 18 whereby I the movement of the rack will rotate said gear 18, the shaft 17, and the gear 20 as well as the pinions 24 and 30. The rack 48 extends through the bottom 14 of the frame and is provided with a finger piece 50 whereby the same may be manipulated. Secured centrally of the inner face of the rack 48 is an inwardly directed yoke 51, the inwardly directed fingers 52- of which are adapted to operate in connection with the arms 42 of themembers 38-39 to move said members together against the tension of the springs 45, as is illustrated in F ig. 5 of the drawing. This result is accomplished in the upward movement of the rack 48 and H1 the downward movement of said rack, the

--springs 45 automatically return the members 38-39 to their inoperative position.

The rack guide 47 is slotted on its inner face as shown at 53 to permit of the passage of the shank of the yoke 51 therethrough.

The operation of my improved thread splicing machine will be readily understood from the foregoing description when taken in connection with the accompanying drawing and the following statement. With the parts in their inoperative position, as shown in Figs. 1 to 4 inclusive, the separate end portions of the threads 2733 are secured The pinion 24 on the -member 21 meshes directly with the gear in the thread holding members 21 and 23 and to the end walls 12' and 13 of'the frame in the manner hereinbefore described and as illustrated in Fig. 3,]after which the rack 48 is grasped by one hand of the operator, it

being apparent that the frame 10 is held by grasping the handle member16 'with the other hand, and said rack is moved upwardly in whichoperation the gears 18' and 20 are rotated comparatively fast, as are also the members 21 and 22 andthe end 2733 together, after which the free ends of said threads are detached or broken off where they connect with the endwalls 12 and 13 of the frame and the rack 48 is then moved downwardly, in which operation the twist originally taken out of said threads by unwinding the sameis again replaced therein by reversing the rotation of the members 21 and 22 and the result of the completion of the downward movement of the rack 48 will be somewhat similarto that diagrammatically illustrated in Fig. 6. In Fig. 6 the thread 27 is indicated in solid black, while the thread '33 is indicated in white, and it will be apparent that theseparate blackv and white threads 27 and 33 are twisted together. p

By first dissecting the separate strands of the thread in the upward movement of the rack 48, as above set out, and then bringing: the dissected end portions of two threads together and again twisting or rewinding' the dissected strands of the thread, the strands are interlocked one with another in such manner as to reinforce and strengthen the spliced thread where connected. In

. other words, a thread spliced inthe manner herein set out will be stronger at the point of splicing than at any other point along the thread. The chief feature of my invention is,-in the fact, that by. splicing the ends of a thread together in the manner set out the sizes or transverse dimensions of the thread is not materially increased and the present method of knottingor joining thev threads by kn'otting, which is undesirable inmanufacturing fabrics, garments or parts of garments is eliminated.-

It will be apparent that while I have illustrated the use of brushes 41' for holding the dissected strands of the thread when unwound together prior to the rewinding of the same, other means may be employed 1 for accomplishingthis result, and various changes in and modifications of the details of construction herein "amine described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages. v
